प्रश्न
Explain why, a freely suspended magnet always points in the north-south direction.
उत्तर
A freely suspended magnet always points towards geographical north and geographical south directions because of the magnetism of the earth. It is assumed that a huge bar magnet is placed at the centre of the earth that causes a freely suspended magnet to align in the directions of north and south poles.
